Question

Name the endocrine gland that produces calcitonin and mention the role played by this hormone.

Answer 1

The thyroid gland also secretes a protein hormone called thyrocalcitoni’n (TCT) which regulates blood calcium levels. TCT is secreted by the ‘C’ cells of the thyroid glands. TCT is a hypocalcaemic hormone which lowers the blood calcium level by increasing calcium deposition in the bones, so checks osteoporosis.
